• Photoluminescence properties of sythesized inorganic materials were evaluated to find possible phosphors for flat panel display applications. Mg, Zn, and Si_3N_4 powders were mixed and sintered at 8O0℃, 1000℃, 1200℃, and 1400℃ under N_2 environment after cold pressed to form Mg_xZn_<1-x>SiN_2, where Tb and Eu were added as luminescent centers. Very sharp emission spectra of Tb^<+3> and Eu^<+2> ions were observed from Mg_xZn_<1-x>SiN_2:Tb and Mg_xZn_<1-x>SiN_2:Eu samples sintered at 12O0℃, 1400℃ and the maximum intensity of emission spectra occurred at wavelength of 550nm(green light) and 470nm(blue light), respectively.
